WILLIAM A. WIGHT, OF TACOMA, WASHINGTON.

STEPLADDER.

Application filed October 29, 1924. Serial No. 746,605.

To all w 7mm it may concern Be it known that 1, WILLIAM A. WIGHT, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of lVashington, have invented a new and useful Stepladder, of which the following is a specification.

This invention relates to stepla'lders and the primary object thereof is to construct a ladder of this character which is light and strong and in which no side sway is possible.

lVith the foregoing and other objects in' view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

in the accompanying drawings Figure 1 represents a side elevation of a stepladder constructed in accordance with this invention;

Fig. 2 is a detail longitudinal section taken on the line 2-2 of Fig. 1; and

Fig. 3 is a detail transverse section taken on the line 33 of Fig. 1.

In the embodiment illustrated a step-section 1 and a brace-section 10 are hingedly connected at their upper ends by a platform 9.0 which is here shown fixedly secured to the step section 1 and with which the bracesection 10 is pivoted.

The brace-section 10 is constructed in any suitable or desired manner of the usual side bars as 11 connected and braced in any suitable manner, cross braces 12 being here shown such as are ordinarily employed in ladders of this character.

The step-section 1 is constructed of two sides bars 2 and 3 which are exactly alike and hence one only will be described in detail. Each of these side bars is composed of two flat boards or bars 4 and 5 between which the ends of the steps 6 are fitted and through which pass connecting bolts 7 which pass also edgewise through the step ends as'is shown clearly in Fig. 3.

Braces 8 are arranged between the upper face of one step and the lower face of the other between the members 4 and 5 of the side bars and as shown, the lower ends of these braces 8 rest on the upper surface of one step adjacent to the ends thereof,-while the upper ends thereof engage the under surface of the adjacent upper step at points in spaced relation with the ends of the upper steps, thereby relieving the connecting bolts 7 of undue strain caused by persons standing on the steps of the ladder.

The usual folding braces 18 connect the step and brace sections of the ladder and a bucket supporting board or platform 14 is also preferably mounted in the upper end thereof.

While this ladder is shown constructed in the form of a step ladder obviously it may be in any other form, the gist of the invention residing in the peculiar construction of the step section which is so formed and braced that there is no possibility of any side sway and yet the weight of the ladder is not materially increased.

I claim In a ladder construction, a step section including side bars, each of the side bars comprising a pair of longitudinally disposed bars steps arranged between the longitudinally disposed bars and secured thereto. brace bars having their lower ends po'si tioned on the upper surfaces of the steps adjacent to their outer ends, said braces having their upper ends engaging the nude;- surfaces of the steps at points in spaced relation with the ends of the steps, and SELi'Ti brace members adapted to engage the longf- I tudinally disposed bars. 7

In testimony that I claim the foregom; as my own, I have hereto aiiixed my signa ture. I 1

WILLIAM A. WVIGHT.
